Hello-
I am looking to obtain an Aperture Iris for my Lunt Engineering 102mm ED refractor to stop down the scope from 102mm to 60mm using a Daystar Quark. I know I can make one from cardboard,plastic,etc.,but would like to get an aperture stop that is manually adjustable and looks professionally made.
Thanks,
Bob

Thanks,Bart-
Nice looking one,but it needs a self made adapter,whichever surprisingly they do not sell per their website. I do not have any idea who would make an adapter for this item. It is really a shame this vendor doesn't sell any kind of adapter,don't you think that is kinda strange? It is like buying a car with no wheels,and the car dealer states you have to make your own wheels!
Best,
Bob

There you see that the iris diaphragm is obviously designed for use with the Baader filter cells. The caption there says that the filter cells are 3D printed, so if you have access to a 3D printer, this might be a way to make your own adapter.

Thank you,Mark and Frank for your help! I have contacted Baader and TelesKop about this issue via email and hope to hear from them soon. I will let you both know the outcome.Yes,Mark,I am hopeful I can just tighten the aperture iris to the 5" dew shield with no problem,which I also asked them about as well if it would work.I hope it is a easy fix,because I would like to use this potentially beautiful aperture stop.
Thanks,guys,
Bob

Just got word from Teleskop Service in Germany: they DO make an adapter to put on my Lunt refractor to put the Baader aperture stop on! I gave them the measurements of my dew shield and am waiting to proceed further. I will post any updates for anyone who is interested in this.

I am still waiting for Teleskop Services to give me total price of the setup. I may just get from Home Depot 2,5" rubber PVC end caps and cut out a 80mm hole on 1 of them,and 60mm hole in the other and stop it down that way,only costing me $12! We will see.
